Photo and Video Chronology — Kīlauea gravity survey and summit webcam maintenance

By Hawaiian Volcano Observatory May 13, 2024

On May 8, 2024, HVO staff conducted a gravity survey around Kaluapele and on May 10, HVO staff conducted maintenance on the F1cam at the summit. 

May 10, 2024 — Maintenance on Kīlauea summit thermal camera

On May 10, HVO staff performed maintenance on the F1cam, the thermal camera at the summit of Kīlauea. Images taken by the camera, which can be viewed here—https://www.usgs.gov/volcanoes/kilauea/f1cam-halemaumau-thermal-image-west-rim-summit-caldera-looking-east—now have a temperature scale.

An HVO scientist takes gravity measurements at a benchmark near a crater in Hawaiʻi Volcanoes National Park. The gravimeter is the small, shoebox-sized instrument, which can measure a change in the force of gravity to one-in-one billionth of the force you feel every day. USGS photo by A. Ellis.

Gravity measurements detect subsurface mass change—for example, magma accumulation or removal beneath the surface. In this way, gravity is a way of detecting changes in the magma reservoir that might otherwise be hidden. This photo shows two gravimeters used one-at-a-time to take measurements. USGS photo by A. Ellis.

On May 8, 2024, HVO staff conducted a gravity survey around Kaluapele (the summit caldera of Kīlauea) in response to current unrest and to supplement a larger survey done in March 2024. Measurements of gravity over time can show how mass is distributed beneath a volcano. At Kīlauea, these routine microgravity surveys help the observatory to monitor volcanic activity and to determine changes occurring below the surface. This photo shows a gravimeter taking measurements near the rim of Kīlauea caldera. USGS photo by A. Ellis.
